Description

Be used for end with connector and be fastened to fastener on the object

Technical field

The present invention relates to a kind of being used for band, particularly the end of watchband is fastened to object, the fastener on the watchcase particularly, described fastener comprises: shell, this shell has the jockey that is connected with described band and is used for described band is connected to two coaxial pins of described object, at least one described pin is slidably mounted between two positions, a position pin withdrawal, another position pin is outstanding so that be bonded on the opening of described object from the wall of shell, and described opening is coaxial so that hold in the described pin another with second opening; Elastic retraction means trends towards described sliding pin is remained on described retracted position consistently; And actuated components, described actuated components links to each other with cam so that described sliding pin is moved to described another position.

Background technology

To be with, especially to be fastened to the problem on the watchcase be the theme of a large amount of solutions to watchband.Utilize the prevailing fastening method of pushing pin to be difficult to placed in position relatively and except that proper tools, also require to wear the unexistent dexterity of most people of the table of band.

Why Here it is has proposed solution since for a long time so that make it possible to change without instrument watchband and require the dexterity of low degree, thereby makes everyone can both change watchband in practice.

The needs of replacing watchband present several occasions in daily life.This needs may come from the simple requirements of the style coupling that makes watchband and activity or clothes.In this case, the driver of dress driving clothes can't be worn over table on their clothes under the situation that does not change watchband length or watchband.Clearly, have only simply and could respond this once very general demand without the fastener that instrument just can be changed watchband.

Yet, the standard that the operation that must to be not only response change watchband of this device is understanded any user.Particularly, if watchband can be easily and do not need instrument just can take off, the very large danger that will exist watchband under the careless situation of wearer, unexpectedly to take off so because table is expensive object, therefore, this danger is unacceptable.Therefore, be intended to make the easier fact of taking off of watchband although exist, this in essence device will have safe coefficient high as the pushing pin fastening system, and this often is a contradiction.

In European patent 876114, a kind of fastener has been proposed, the inner end engages of its cam and two sliding pins, wherein said two sliding pins press against on the cam by spring.According to an embodiment, cam along install slidably with the direction of the slip axis traversed by of described pin and itself by spring to external pressure.In this position, cam with described pin to being extrapolated to the position of assembling mutually with the cornuate secured opening of watchcase.For these pins are discharged from these openings, it is just enough to apply a pressure on the slide unit of supporting cam wheel.Now, this pressure may be unexpected, has produced the watchband and the outer danger that separates of expressing the meaning thus.

Above-mentioned same document also proposes to be used to prevent the device of this danger.One in these devices is constructed such that the cam control assembly with round button shape is in the position, two angles around its axis of rotation, and one of them position, angle is corresponding with the axial lock allocation.Because this cam control button may have very little diameter, therefore, its rotation is problematic at least under the situation that does not have instrument to assist.The document has also proposed the rotating cam by the control of rotation control assembly, but this solution needs to use the screwdriver rotating cam clearly.

Therefore, can notice, in the prior art, there is not to satisfy the technical scheme of whole demand conditions, or having any other band of any other object, this scheme is fully manually control, does not have instrument and has overall safety with respect to the accidental separation danger between watchband and the watchcase.

Summary of the invention

Therefore, the objective of the invention is to address the aforementioned drawbacks at least in part.

For this reason, theme of the present invention is a kind of according to claim 1 being used for band, and especially the end of watchband is fastened to object, especially the fastener on the watchcase.

The separation watchband is the result that will separate with shell with the actuator arm that cam links to each other with shell, thereby must hold the free end of actuator arm and it is separated with shell, this separation can not unexpectedly be carried out, particularly, favourable mode is, if actuator arm is placed on the side of shell, the side of described shell will lean against on wearer's the arm of table of band.As a result, in this case, the table that band arranged must at first be taken off so that control arm moved to the position of separating with the shell that installs.

Optimal way is, control arm is maintained at and is connected device and depresses the position that comes on the shell.Favourable mode is, these jockeys by cam second, the spill arranged in form, between the first and actuator arm of cam, so that hold the inner of the described pin in the concave portions that is pressed into cam, thereby not only needing for example to act on by the nail between the shell that is inserted in described arm and device is on its arm that pushes the position, and need overcome the connection power of control arm.For this reason, preferably be formed with the thumbnail groove in the surface in the adjacently situated surfaces of arm or shell so that make and nail can be inserted wherein, thereby rise control arm.

The specific embodiment

Fig. 1 comprises having the fastening shell 1 of parallelepiped shape substantially to the fastener shown in Fig. 4, the length in the space of the horn shape ledge 2 of the corresponding substantially separation watchcase 3 of the length of described fastening shell 1.In the illustrated embodiment, fastening shell 1 is fixedly connected to the pushing pin secure component 4 of the watchband 5 of certain-length.Under the situation of metal hinge watchband, clearly, secure component 4 can be configured with the complementary shape of the adjacent connector that can hold watchband.As a result, in this example, be configured as the secure component 4 that holds the belt-type watchband and can have the Any shape that is suitable for being intended to the watchband that links to each other with watchcase.Like this, under the situation of connector watchband (link bracelet), it can have corresponding with the connector of watchband at least in part profile so that cooperate with watchband.

The mechanism of fastener itself more specifically illustrates by Fig. 2 and Fig. 3, and wherein fastener is represented with two positions, moving position and inertia position.Described mechanism comprises two coaxial pins 6,7, and each pin is slidably mounted in two coaxial aperture 8a, 9a, 8b, the 9b.Hole 8a, 8b have bigger diameter than hole 9a, 9b and are respectively applied for large diameter rear portion 6a, the 7a of sliding pin 6 and 7.Be formed on connecting pin 6,7 rear portion 6a, 7a bearing-surface and respectively the annulus between the bearing-surface of connecting hole 8a, 9a and hole 8b, 9b be respectively applied for and hold two return

helical springs

10,11, described two return helical springs are compressed between two bearing-surfaces and thus axial force are applied on each pin 6,7, described axial force is tending towards oppressing the inner of two pins 6,7 to be leaned on each other mutually, as shown in Figure 2.

The axle 13 that arm 12 takes up solid shell 1 in one end thereof is hinged.With respect to arm 12 horizontal expansions, shell 1 has opening 1a and is used to allow cam 14 to pass through cam 14 to the direction of shell 1.Then, cam 14 can rest between two round-shaped the inners of having of pin 6,7, forms thus from their center to the space that their periphery increases, wherein described two inner adjacency at their center.This shape allows the end 14a of cam 14 to contact with each periphery of circular surface.Because this layout, when power F is applied on the arm 12, a part that is applied to this power on the arm is delivered to two pins 6,7 with the form of two relative power F1, F2, described two relative power F1, F2 are tending towards resisting power that return

spring

10,11 is applied on these pins 6,7 and move in opposite directions pin 6,7, thereby make it possible to pin 6,7 is moved to the position shown in Fig. 3, in the position shown in Fig. 3, outer end 6b, the 7b of these pins is outstanding and penetrate in the respective openings in the horn shape ledge 2 of watchcase 3 from fastening shell 1, thereby guarantees the fastening of watchband 5.

Between the end of cam 14 14a and arm 12, if the cross section of cam 14 is circular, cam 14 has a part 14b, if perhaps the cross section of cam 14 is a rectangle, cam 14 has two symmetric part 14b, and described part 14b is a spill, is used to hold the circular inner of pin 6,7.Because this second portion 14b of cam, it is relative with separating of fastening shell 1 with arm 12 and owing to the return force of spring remains on the restraint location shown in Fig. 3 with this arm to be applied to relative power on the cam 14 by

return spring

10,11 by pin 6,7.

Naturally, if be preferred, for example will stop other jockey of between the edge of the free end of arm 12 and fastening shell 1 use without any things so with arm 12 this method on the fastening shell 1 of remaining on.

Yet, need to prove that this method for optimizing that arm 12 is connected the bonding station of pin 6,7 has additional advantage.After long inertia, the pin 6,7 of fastener emits to be had owing to blocking the motionless danger that is fixed.If the user simply withdraws from pin 6,7 is kept the cam of separation, and at first do not apply positive motion on pin, pin will be maintained fixed motionless so.Except the fact that the recess 14b of cam 14 can be held in place arm 12, release pin 6,7 in the time of also can on pin 6,7, applying positive motion and separate with fastening shell 1 with convenient arm 12, this allows

return spring

10,11 to act on these pins 6,7 subsequently, may not withdraw otherwise sell 6,7.

Can overcome the power relative with its opening in order can manually to apply on arm 12, thumbnail groove 15 (Fig. 4) preferably is formed on one of them surface of adjacently situated surfaces of actuator arm 12 or fastening shell 1.

Except the advantage of having mentioned, may have been noted that on the basis of having read the foregoing description fastener does not need the modification of watchcase or watchband.Pin 6,7 can replace common pushing pin simply; For watchband, be equipped with when preferably delivering goods according to fastener of the present invention, be ready to thus be connected on the watchcase.

As variation, for example, the actuated components 16 that the actuator arm 12 that at one end is hinged to fastening shell 1 can be installed to by guiding part 17 on the fastening shell 1 replaces, and guiding part 17 is used for engaging with the guide element 18 of complementation, and be fixedly connected to fastening shell 1, as shown in Figure 5.

Also can imagine such variation (not shown), wherein sell and have only one will be slidably mounted in the fastening shell 1 in 6,7 that another pin is fixed on from the outstanding position of shell.In this case, fixing pin will at first be bonded in the opening of horn shape ledge of watchcase 3 and have only another pin to be moved by cam 14, and cam 14 activated parts 12 and moves.
